矿物包裹体在沉积学中的应用

矿物包裹体是在沉积成岩成矿过程中被捕获的原始沉积成岩成矿流体介质,对包裹体的研究不但可以提供诸多物理化学条件(温度、压力、含盐度、逸散度、pH值、Eh值、密度、体积等)的重要信息,而且有助于了解沉积成岩成矿流体介质的性质、组分、状态以及它们在时间和空间上的演化规律。本文系统介绍并探索矿物包裹体在沉积岩成因、成岩作用、成岩微区分析、成岩条件、成岩环境、成岩演化过程、有机质热演化和沉积盆地分析等方面的应用。

APPLICATIONS OF MINERAL INCLUSION IN SEDIMENTOLOGY

Mineral inclusion is a sort of original fluid medium which is trapped during sedimentation, diagenesis and mineralization. It can be used to study not only various physical and chemical conditions (temperature,pressure,volume,density, oxidizing reduction potential, salinity, acidity parameter etc.),but com position, property, state and relative evolution in time and sapce as well. This paper introduces and deals with that how tlie inclusion applications are used in genesis of sedimentary rocks,diagenesis,analysis of diagenetic microprovince,diagenetic process,thermal-evolution of organic matte,and the analysis of sedimentary basin.
